This invention relates generally to engine mountings and has particularreference to means for securing internal combustion engines for motorboats to an engine bed. I

At the present time, it is usual to secure internal combustion enginesto engine frame bed timbers through'the medium of headless lag screws,threadedat their upper ends to receive securing nuts, and these lagscrews are, to all intents and purposes, substantially immovable. Tomove the engine, it is necessary, therefore, to lift the same to freethe en 'ine from the lag screws. It is usual to incline an enginedownwardly towards the stern of the boat, and it will be apparent that,unless the engine is elevated at the same angle of inclination as thelag screws, the latter are often-times bent and sometimes even broken,and the threads on the lag screws are often stripped. In addition tothis, it will also be apparent that, when an engine is secured byimmovable lag screws, it is practically an impossibility to shift theengine on itsbed, should it be desired to do so.

It is desirable to provide some means for securing an engine to a bed insuch a manner that it may be moved thereon without the necessity ofbeing lifted. t is also desirableto provide a securing means for anengine which, during the elevation of an engine, will not becomedistorted, bent or broken.

One object of the present invention, therefore, is to provide a securingmeans for an engine of a motor boat which will permit the engine to bemoved on the engine bed.

Another object of the present invention is to provide a securing meansfor motor boat engines which, when freed from their securing engagement.with the engine, are confined or retained inan easily accessible placeand out of direct engagement with the engine.

A further object of the invention is the provision of means comprisingan insert for mounting securing bolts for an engine whereby, when saidbolts are not in securing position, they are retained out of contactwith the engine.

A still further object of the present invention is the provision of asocket casting for receivingthe securing bolts of an internal combustionengine. I

Anotherobject of the invention is the provision of a casting forreceiving a securing bolt; the casting being so formed as t-oper mit thebolt to drop and to be retained therein. 7

Other objects and advantages of this invention will be apparent from thefollowing description taken with the accompanying drawings in whichFigure l is a side. elevation of a portion of a boat showing the enginebed and an engine secured thereto by the means of the present invention;

Fig. 2 is a front elevation of the invention in. use;

Fig. 3 is a sectional view on the line 3 3, Fig. 2; and

'Fig. at is a perspective view of the socket casting.

Referring now particularly to'the drawings, in which similar charactersof reference designate similar parts in the several views, the inventionincludes the provision of securing means for engines which may bereleased to be freed from their engagement with the en 'ine, to permitthe latter to be moved on the engine bed or lifted. In Fig. 1 a boatkeel is indicated generally at A, and B indicates generally the enginebed secured to the keel by suitable fasteners such as bolts 2. As

isusual, the bed slopes downwardly toward the stern of the boat andsupports the engine C at an incline; the enginebeingprovided with asupporting flange .4; which rests on the upper edge 6 of the bed.

The invention comprises essentially a hollow casting which is shownclearly in Fig. 4;.

gine bed as clearly shown in F1 2 2; the bed being provided withrecesses complementary cesse's suitable'fasteners such as screws 24are'employed.

f The attaching flange 4 of the engine is provided "with bolt holeswhichare alined;

with theslot 14 in the upper face ofthe body portion? of thecasting, andbolts 26 are em- ,ployed for securing the engine tothe bed; the

with a slot communicating with the open,

bolts having heads 28 which are received 5 within the body portion 7, asclearly shown attached to the engine bed. With the engine secured to thebed as shown 7 in Fig. 3, it is apparent that the bolts 26are I v inFig. 2, and the'shank of thebolts extending upwardly through the neck 16and "through the bolt holes in the flange 4 to receive nuts 30, wherebythe engine is securely retained against rotation by means ofthe lugs'18,but, should it be desired to move the engine on the bed, the nuts 30 arebacked ofl of. the bolts 26, whereupon the latter drop in the bodyportion in the rear of the lugs 20,

thereby preventing loss of the bolts.

From the above description it is believed hand.

An insertof the described compris- I in a hollow bodportion having one open ad e andhaving upper surface provided side, aflange extending upwardl from the upperxsurjacefadjacent the slot tiieretainingmeansin the body portion, and at taching ears formed with thebody portion; In witness whereof I have hereunto set my JOHN J.MoBR-IDE;

' that the construction andv operation of the I 7 device of the presentinvention will be fully apparent to those skilled in the art, attentionbeing called to the fact that the device of thpresent invention providesa means for securing an engine to an engine bed, which 1, meansaaresoformed that upon release of the nuts 30 and the resultant dropping ofthe bolts'26iinto the socket,,ethe engine may be freely moved on the bedor may be lifted ver- I tically directlyfrom the be'dand, during such 7.r

lifting, the bolts 26 are out of engagement withithe flange 40f theengine, thereby eliminatingl any'possibility of distortion of the boltsor stripping of the'threads.

The drawings herein disclose the preferred embodiment of the'i'nvention,but it is to be understood that they are merely by way, or example andthat various changes in the form "and roportions of the device may bemade within the scope of the appended claims withtlon. t p p \Vhat isclaimed is:
